Backup exec 2012 install on windows 2003 sbs sp2 mdac mismatch

I am trying to install backup exec 2012 sbs on windows 2003 sbs sp2 but it will not install. after numerous calls to symantec support they have finally said i have a mdac mismatch issue which i accept that there is one but the mismatch is above the stated version and i have traced it to an update namely kb2419635 which updated the following dll's to later versions.

Dll expected found

msaco 2.82.3959.0 2.82.4795

msadcs " "

msado15 " "

msadomd " "

msadox " "

msjro " "

odbc32 3.526.3959 3.526.4795

msxml3 8.801185.0 8.100.1051.0

Would this cause backup exec install to fail and even if i remove the update manually then because it is a security update then it would then need to be reinstalled causing the backup exec install/services to fail.
